John,
The original as found in the sipx library which uses PCRE:

// UsernameAndPassword
//   requires and matches the trailing '@'
//   $1 matches user
//   $2 matches password
const RegEx UsernameAndPassword(
    "("
       "(?:"
          "[a-zA-Z0-9_.!~*'()&=+$,;?/-]++"
       "|"
          "%[0-9a-fA-F]{2}"
       ")+"
     ")"
    "(?:" ":"
         "("
         "(?:"
             "[a-zA-Z0-9_.!~*'()&=+$,-]++"
         "|"
            "%[0-9a-fA-F]{2}"
         ")*"
       ")"
     ")?"
     "@"
                                    );

This doesn't take in boost::regex.
